Triplet du calcium

Triplet du calcium

Le triplet du calcium est un ensemble de trois raies spectrales du calcium ionisé observées en spectroscopie infrarouge aux longueurs d'onde de 849,8, 854,2 et 866,2 nm[1]. Le triplet est généralement observé en absorption chez les étoiles de type spectral A à M.
